WAVE FORECASTING
The theoretical determination of future wave characteristics, usually from observed or predicted meteorological
phenomena.
WAVE FREQUENCY
The inverse of wave period.
WAVE FREQUENCY SPECTRUM
Distribution of wave energy as a function of frequency.
WAVE, GRAVITY
See GRAVITY WAVE.
WAVE GROUP
A series of waves in which the wave direction, wavelength, and wave height vary only slightly. See also GROUP
VELOCITY.
WAVE HEIGHT
The vertical distance between a crest and the preceding trough. See also SIGNIFICANT WAVE HEIGHT.
WAVE HEIGHT COEFFICIENT
The ratio of the wave height at a selected point to the deepwater wave height. The REFRACTION COEFFICIENT
multiplied by the shoaling factor.
WAVE HINDCASTING
See HINDCASTING, WAVE.
WAVE, INFRAGRAVITY
See INFRAGRAVITY WAVE.
WAVE, IRROTATIONAL
See IRROTATIONAL WAVE.
WAVE, MONOCHROMATIC
See MONOCHROMATIC WAVES.
WAVE OF TRANSLATION
A wave in which the water particles are permanently displaced to a significant degree in the direction of wave
travel. Distinguished from an OSCILLATORY WAVE.
WAVE, OSCILLATORY
See OSCILLATORY WAVE.
WAVE PEAK FREQUENCY
The inverse of wave peak period.
WAVE PERIOD
The time for a wave crest to traverse a distance equal to one wavelength. The time for two successive wave crests
to pass a fixed point. See also SIGNIFICANT WAVE PERIOD.
WAVE, PROGRESSIVE
See PROGRESSIVE WAVE.
